🛠 Professional Drilling Tips
For hard materials such as stainless steel, drill a small hole with 3-6mm drill bit first, then expand the hole with a large drill bit.
The rotating speed of electric drill is recommended to be 80-120r/min when drilling hard metals, avoid high speed to burn the drill bit.
Add coolant or cutting fluid during drilling to reduce temperature and extend the service life of drill bit.
For drilling holes with diameter more than 10mm, it is recommended to use a bench drill with power above 500W.
⚠️ Warm Tips
Please choose the appropriate drill bit size according to your drilling needs.
Keep the drill bit dry and clean after use, store it in a cool and dry place to prevent rust.
Manual measurement may have an error of 0.1-0.3mm, please understand.
The color of the product may be slightly different due to different display and lighting effects.
